That looks great, nice job with a complex tartan!

If I understand your description of buttonhole alignment, remember that (unless you are really skinny) when you wear it the buttons will tend to move over to the far edge of the hole, not stay nicely centered. I think that is what you found out, just restating it for others who may be tackling a vest for the first time.

The Lodge "bling" really makes it pop, too!
